Customer feedback reports a solid build, good fit and perceived suitability for EV-charging setups, but also raises a durability concern, including reports of the plastic melting after about a year. That concern matters for an electrical receptacle, while the listing itself says this model is not recommended for EV charging. Overall ratings lean strongly positive, but ratings alone do not establish durability or suitability for a particular installation.
Positive themes
- Customers report good build quality and fit.
- Some customers describe using it with EV chargers.
Negative themes
- Customer feedback includes reports that the plastic melted after about a year of use.
